Model analysis of flakeboard variables
1991
Suchsland, O. | Xu, H.
A model consisting of thin narrow veneer strips was used to demonstrate the development and the consequences of horizontal density variations in flakeboards. The durability of the model (survival at severe exposure conditions) and, by implication, the durability of flakeboard are substantially affected by the severity of this horizontal density variation, which during exposure of the board to severe conditions generates normal stresses on gluelines, resulting in glueline failure and excessive thickness swelling. An increase in resin content can overcome these difficulties to some extent. Heat treatment of the veneer strips reduces gluebond quality, possibly by wood surface modification. Heat treatment of finished boards appears to be beneficial.
